When working with arrays in Python, it is important to ensure that the elements in the array are of the correct data type. If the input array is not of type double, it can lead to issues such as unexpected results or errors in the code. Let’s take a look at an example to illustra...
1. The pointer of an array in Python with the length of len(A) starts from 0 to len(A)-1, rather than 1 to len(A). Pay particular attention when the pointer is in the while loop, where the maxium value of the pointer is len(A)-1, otherwise the list overflows. 2. Since we ...
